# How do you solve 5+ x = 3x + 25?

Jun 20, 2018

$x = - 10$

#### Explanation:

First, subtract $20$ from both sides of the equation so that the right side of the equation only has one term. This will give you

$- 20 + x = 3 x$

Next, subtract $x$ from both sides so that only one side has a variable. Now you should have

$- 20 = 2 x$

The last step is to divide both sides of the equation by $2$, which will give you

$- 10 = x$

You can double check to see if this is the solution by substituting $x$ with $- 10$ in the original equation.
